Abstract

The present invention relates in part to nucleic acids, including nucleic acids encoding proteins, therapeutics and cosmetics comprising nucleic acids, methods for delivering nucleic acids to cells, tissues, organs, and patients, methods for inducing cells to express proteins using nucleic acids, methods, kits and devices for transfecting, gene editing, and reprogramming cells, and cells, organisms, therapeutics, and cosmetics produced using these methods, kits, and devices. Methods and products for altering the DNA sequence of a cell are described, as are methods and products for inducing cells to express proteins using synthetic RNA molecules, including cells present in vivo. Therapeutics comprising nucleic acids encoding gene-editing proteins are also described.

First claim

What is claimed is:

1. An in vivo method for treating dystrophic epidermolysis bullosa, comprising
delivering a synthetic RNA encoding a gene-editing protein that targets a COL7 gene to a patient in need thereof and
delivering a COL7 repair template to the patient, thereby editing the COL7 gene, wherein:
the synthetic RNA and the COL7 repair template are delivered to the patient's keratinocytes by injection to the epidermis.

2. The method of claim 1 , wherein the gene-editing protein corrects or eliminates, either alone or in combination with one or more other molecules or gene-editing proteins, a mutation that is at least partially responsible for a disease phenotype.

3. The method of claim 1 , wherein the COL7 repair template is a single-stranded DNA molecule or a double-stranded DNA molecule.

4. The method of claim 1 , wherein the COL7 repair template does not contain a binding site of the gene-editing protein.

5. The method of claim 1 , wherein the gene-editing protein targets a nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 78.

6. The method of claim 1 , wherein the gene-editing protein is selected from the group consisting of a nuclease, a transcription activator-like effector nuclease (TALEN), a zinc-finger nuclease, a meganuclease, a nickase, and a clustered regularly interspaced short palindromic repeat (CRISPR)-associated protein.

7. The method of claim 1 , wherein the synthetic RNA molecule further comprises one or more of a 5′-cap, a 5′-cap 1 structure, and a 3′-poly(A) tail.

8. The method of claim 1 , wherein the synthetic RNA and the COL7 repair template are delivered to a part of the skin that is disrupted or removed.

9. The method of claim 8 , wherein the disrupted or removed part of the skin is the stratum corneum.

10. The method of claim 1 , wherein the injection comprises a patch configured to deliver a nucleic acid to the epidermis.

11. The method of claim 10 , wherein the patch comprises a micro-needle array.

12. The method of claim 11 , wherein at least two needles in the micro-needle array form part of a high-voltage circuit.

13. The method of claim 12 further comprising applying a transient electric field in the vicinity of the keratinocytes.

14. The method of claim 1 , wherein the synthetic RNA and the COL7 repair template are not directed to the patient's dermis and/or wherein the synthetic RNA and the repair template are not directed to the patient's fibroblasts.

15. An in vivo method for treating epidermolysis bullosa, comprising
delivering a synthetic RNA encoding a gene-editing protein that targets a COL7 gene to a patient in need thereof and
inducing a single-stranded or double-stranded break in the COL7 gene of the patient's keratinocytes, thereby eliminating a mutation that is at least partially responsible for a disease phenotype, wherein:
the synthetic RNA is delivered to the patient's keratinocytes by injection to the epidermis.

16. The method of claim 15 , wherein the gene-editing protein is capable of targeting a nucleic acid sequence that encodes the amino acid sequence of SEQ ID NO: 78.

17. The method of claim 15 , wherein the gene-editing protein is selected from the group consisting of a nuclease, a transcription activator-like effector nuclease (TALEN), a zinc-finger nuclease, a meganuclease, a nickase, and a clustered regularly interspaced short palindromic repeat (CRISPR)-associated protein.

18. The method of claim 15 , wherein the synthetic RNA further comprises one or both of a 5′-cap structure and a 3′-poly(A) tail.

19. The method of claim 15 , wherein the synthetic RNA further comprises one or both of a 5′-cap 1 structure and a 3′-poly(A) tail.

20. The method of claim 15 , wherein the synthetic RNA is delivered to a part of the skin that is disrupted or removed.

21. The method of claim 20 , wherein the disrupted or removed part of the skin is the stratum corneum.

22. The method of claim 15 , wherein the injection comprises a patch configured to deliver a nucleic acid to the epidermis.

23. The method of claim 22 , wherein the patch comprises a micro-needle array.

24. The method of claim 23 , wherein at least two needles in the micro-needle array form part of a high-voltage circuit.

25. The method of claim 24 further comprising applying a transient electric field in the vicinity of the keratinocytes.

26. The method of claim 15 , wherein the synthetic RNA is not directed to the patient's dermis and/or wherein the synthetic RNA is not directed to the patient's fibroblasts.
